core is too small in proportionto the other dimensions, the total flux, and consequently theinduced voltage of the secondary, will be low. It has been foundthat as the iron in the coil is increased, the secondary voltage ofthe coil is increased. With a large core the reluctance is less andit is… … f/^T£J5ISUF^£C B/iTT£^r Fig. 42.

Increasing the core diameter alsoincreases the average length of turn of the coils and accordinglyincreases the weight of copper and the cost. It is thereforeapparent that unless too large a core…
